Start menu has consistent but totally useless and bizarre arrow behaviour: Part 3
Press Windows Key. Default keyboard focus is an invisible label ABOVE your username. Press up and you go to "All Apps", or press down and you go to your username. This is a valid-enough assumption. Move focus to your username.
Now that focus is on your username, where would you expect focus to move if you press right? The category name above your apps, right? Correct. That's what happens. Now, where do you think focus will be when you press left? Back on your username? WRONGO. You will be on the first app of the "Most Used Apps" list.
Basically, the focus on the right column always starts on the category name above the pinned apps. This is not useful because you almost never want to be changing that and you almost always want to be launching your first pinned app. The focus on the left column is generally on the first most used app, which is pretty useful, but the focus is not there if it's your first time moving focus onto the menu, in which case it's on your username, which is generally not useful because you want to launch apps more often than you want to switch users.
You will remember from my previous complaints about the Start menu arrow key behaviour that this is nothing new. If you have your keyboard focus on an app and press right, if the app has a jump list you go to the jump list. If you press right on a jump list, you don't go to pinned apps. But if you press right on an app with no jump list, you go to the category label above the pinned apps.
Start Menu does not have consistent tab behaviour
Press Windows Key. As above, your focus is on an invisible label ABOVE your username. If you press tab, it is customary that your focus goes to the next object you can focus on. In this case, it'd be your username. Perfect. Now press tab again. Do you think this will go to your most used or applications? Should tab stay within the column or go to the next column? The answer is that it goes to the first application in most used. Makes sense. Press tab again. Where do you think it goes?
The answer to this one depends. If the first app on your most used has a jump list, then it goes to the jump list. This kinda makes sense, it's the next object you can interact with in the same category of objects. But if your first app does not have a jump list (or if you tab from the jump list) it jumps over all the rest of your most used apps. Even if you press keyboard down to your second most used app and press tab, the behaviour is the same; if it has a jump list, bring you to the jump list. If not, skip all the other most used apps. So, on this menu, does tab switch between sections, or between items within a section? There's no consistent answer.
Where do you think tab ends up? File Explorer? Nope. It skips that one for some reason. You get settings. Okay, press tab again. Power. Not sure why it jumps to the next item instead of the next section, but whatever. Press tab again: All Apps. Makes sense. Press tab again, where to now?
If you guessed the first app of your pinned apps, you're wrong. It goes to the label of the first group of pinned apps. That doesn't really make any sense. Okay, where do you think tab goes now? Would you guess the first pinned app? Nope. Would you guess the next label of pinned apps? Nope. Actually, if you tab here, your focus just goes to the invisible box above your username. Tab again and you're back on your username.
